“It's no secret that Mame is someone we have been looking to bring to the Club for some time”

Tony Scholes

"Mark Hughes has wanted to sign Mame since he took over as manager last year. We tried to get him last summer and made another attempt in January, so we're naturally delighted to have finally secured his services.

"He has been a tremendous success in Germany as his record underlines and he is keen to return to England make an impact in the Premier League. We're pleased to be able to give him the platform to hopefully achieve that ambition.

"Mark is looking forward to working with Mame, who is himself excited about the prospect of linking up with rest of the squad in July."

As well as increasing their fire-power with the addition of Diouf the Potters have also strengthened their defence by signing centre-back Dionatan Teixeira.

The 21-year-old joins the club from Slovakian side Dukla Banská Bystrica, and he has signed a three-year-deal at the Britannia.

"We have been following Dionatan's progress for some time and we're delighted to have secured his services because there's no doubt he's a talented player with a great deal of potential."
